ROTARY PLANE.

Specification of Letters Patent.

Patented July 29, 1919.

Application filed February 4, 1919. Serial No. 274,981.

To all whom it may concern:

Be it known that we, BUREN E. TEMPLE- TON and GEORGE T. ENGLAND, citizens of the United States, residing at Wessington Springs, in the county of Jerauld, State of South Dakota, have invented a new and useful Rotary Plane, of which the following is a specification.

This invention relates to a rotary plane for use primarily in planing rubber from pneumatic and solid tires. Heretofore it has been the practice to use for this purpose rotary rasps, emery IWhGGlS and wire brushes, but they have been found to be objectionable because of their construction. The emery wheel becomes glazed and, at high speed, dangerous. The rotary rasp is too heavy and tears and scrapes the rubber from the tire. It also soon becomes dull and inei'ficient. The wire brush is inefficient because it cannot cut the hard treads.

One of the objects of this invention is to provide a light and fast cutting plane which will produce a continuous cut across the tread, leaving the surface in perfect condition to receive and hold the cement preparatory to applying the retreads. With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claim, it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention as set forth in the appended claim.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a side elevation of the plane.

Fig. 2 is a plan view of a portion thereof.

Copies of this patent may be obtained for Fig. 3 is a section through a portion of the plane on line 33, Fig. 1.

Referring to the figures by characters of reference, 1 designates a wheel that can be made of one or more thicknesses of wood bolted together as shown at 2, the edges of the wheel being preferably beveled as shown. The periphery of the wheel is provided with a band 8 of metal having side flanges 4 bearing against the beveled portions of the wheel. Extending through the band and into the wheel 1 is a series of studs of metal, shown at 5, these studs being extended spirally around the wheel so that, as shown in Fig. 2, each stud has its outer or free end extending into the paths of the next adjoining studs in front and rear thereof. The studs are preferably tapered as shown and the ends thereof are flat.

In using the device it is secured to a lathe or other device so as to be rotated at a high speed. The tread casing to be planed is then adjusted against the rotating studs. Each stud will plane off a narrow strip of rubber and the next stud following will do likewise, all of the studs cooperating to plane a smooth surface which will properly prepare the casing for retreading. The de vice is self clearing and will not clog or choke and thus become inefficient.

What is claimed is I A rotary plane including a wheel, a metal band upon the periphery of the wheel, and a spiral series of planing studs extending through the band and from the wheel, each stud extending into the paths of the next adjoining studs in front and rear thereof.

In testimony that we claim the foregoing as our own, we have hereto affixed our signatures in the presence of two witnesses.
